Event 1209 (Warning)

How important is this event?

Description

It turns out that event is only recorded if ADWS can’t read the ports that AD LDS is configured to use for LDAP and Secure LDAP (SSL). In our test environment, we deleted those values and restarted the ADWS service, and sure enough, those pesky warning events started getting logged.
The following registry values are read by ADWS:

*UPDATE* I’ve just had to do this fix for the latest installation of vCentre and as mentioned by people in the comments below the path is now HKLM\System\CurrentControlSet\Services\ADAM_VMwareVCMSDS\Parameters , the | SSL Port value is created as a REG_SZ instead of REG_DWORD and the value is empty. So you need to delete this and recreate it as a REG_DWORD with the value 636.

Associated Messages

In my case the Port SSL Type was REG_SZ in the registry with a blank value.
According to the instruction it should be a REG_DWORD with the dec. value of 636. So i did removed the wrong one and put in the right one, restarted the service and the error disappeared.

Active Directory Web Services
Q: I’m seeing the following warning event recorded in the Active Directory Web Services event log about once a minute.

I can’t find any Microsoft resources to explain why this event occurs, or what it means.

A: Well…we couldn’t find any documentation either, but we were curious ourselves so we dug into the problem. It turns out that event is only recorded if ADWS can’t read the ports that AD LDS is configured to use for LDAP and Secure LDAP (SSL). In our test environment, we deleted those values and restarted the ADWS service, and sure enough, those pesky warning events started getting logged.

Verify that the registry values described above exist and have the appropriate values. Also verify that the NT AUTHORITY\SYSTEM account has permission to read the values. ADWS runs under the Local System account.

Once you've corrected the problem, restart the ADWS service. If you have to recreate the registry values because they've been deleted, restart the AD LDS instance before restarting the ADWS service.

Thanks for sending us this question. We’ve created the necessary internal documentation, and if we see more issues like this we’ll promote it to the Knowledge Base.
